if all cables have been disconnected. 

 

Do not spill food or liquids on your equipment. 

 

Before you clean your equipment, disconnect it from the electrical outlet. Clean your device with a 

soft cloth dampened with water. Do not use liquids or aerosol cleaners, which may contain flammable 

substances. 

 

Clean the monitor display with a soft, clean cloth and water. Apply the water to the cloth, then 

stroke the cloth across the display in one direction, moving from the top of the display to the bottom. 

Remove moisture from the display quickly and keep the display dry. 

 

Long-term exposure to moisture can damage the display. Do not use a commercial window cleaner 

to clean your display. 

 

If your equipment does not operate normally - in particular, if there are any unusual sounds or 

smells coming from it - unplug it immediately and contact an authorized dealer or service center. 

 

Protecting Against Electrostatic Discharge 

Electrostatic discharge (ESD) events can harm electronic components inside your equipment. Under certain 

conditions, ESD may build up on your body or an object, such as a peripheral, and then discharge into 

another object, such as your computer. To prevent ESD damage, you should discharge static electricity 

from your body before you interact with any of your equipment’s internal electronic components, such as a 

memory module. You can protect against ESD by touching a metal grounded object (such as an unpainted 

metal surface on your computer’s I/O panel) before you interact with anything electronic. When connecting 

a peripheral (including handheld digital assistants) to your equipment, you should always ground both 

yourself and the peripheral before connecting it. In addition, as you work inside the equipment, periodically 

discharge any static charge your body may have accumulated. 

 

You can also take the following steps to prevent damage from electrostatic discharge: 

 

When unpacking a static-sensitive component from its shipping carton, do not remove the 

component from the antistatic packing material until you are ready to install the component. 

 

Just before un wrapping the antistatic package, be sure to discharge static electricity from your 

body. 

 

When transporting a sensitive component, first place it in an antistatic container or packaging. 

 

Handle all electrostatic sensitive components in a static-safe area. If possible, use antistatic floor 

pads and work bench pads.
